CLAMP FOR CULTIVATOR-STANDARIDS.

Specification of Letters Patent.

Patented Apr. as, rare.

Original application filed September 18, 1915, Serial No. 51,394.Divided and this application filed January 6, 1916. Serial No. 70,647.

To all whom it may concern:

Be it known that I, EDGAR W. BENSON, a citizen of the United States,residing at Richmond, county of Contra Costa, and State of California,have invented certain new and useful Improvements in Clamps forCultivator-Standards, of which the following is a specification.

My invention relates to clamps for cultivator standards and has for itsobject the provision of an improved cam lever and hail, quick detachableand adjustable connection, and an improved standard construction, saidparts being adapted for cooperation in a novel manner to secure thestandard to the frame of the cultivator, and also to permit quick andeasy adjustment thereon or detachment therefrom.

The present application is a division of my application for cultivatorstandard and shovel, filed September 18, 1915, Serial No. 51,394, butthe present invention is not limited in its use to the improved shovelconstruction shown in that application.

The embodiment of the invention which is set forth hereinafter and shownin the accompanying drawings is to be considered as illustrative, ratherthan restrictive, of the scope of the invention, as the latter issusceptible of modification without departing from the essentialprinciples thereof.

In the accompanying drawings: Figure 1 is a perspective of the inventionas applied to a section of cultivator frame, the shovel shown being onlyone of various forms which may be used and forming no part of myinvention; and Fig. 2, a detail of the upper part of the standard andthe clamping means, detached from the cultlvator frame.

The standard 1 which carries any suitable shovel or earth treatingimplement 2 has a looped or rebent upper end 3 adapted to snugly, yeteasily, fit the flat portion 4 of the cultivator frame. The loopedportion 3 is provided with a rounded or 1nclined cam surface 5 at itsfree end and on its upper face. A bail 6 is pivoted at 7 to oppositesides of the standard 1. A cam lever 8 has its cam portion 9 Journaledon the upper cross portion 10 of the bail 6 and is adapted to bearagainst the inclined or rounded cam surface 5. When the lever 8 israised, the tension is released and the looped portion 3 is thensufficiently free of the frame part 4 to permit the standard 1 to beslid lengthwise of said frame part 4. hen the lever 8 is pressed down,as shown in Fig. 1, the cam portion 5 exerts tension on the bail 6 and,due to a certain amount of sprlnginess or resiliency in the upper partof the looped portion 3, the latter is clamped firmly against the framepart 4. The lever 8 will remain in its lowered position, as shown inFig. 1, due to the pivotal part 10 of the bail 6 being slightly off-settoward the free end of the lever. The bail 6 bears against the rear edgeof the frame part 4 and prevents any forward displace ment of the loopedpart 3. The pressure is taken, mainly, on the yoke portion of the part3.

The construction described obviates the necessity for bolting orotherwise clamping the standard 1 to the frame part 4 and, whileaflording a secure connection therebetween, permits rapid and easyadjustment.

The bail 6 is of such length and the cams 5 and 9 of such height thatwhen the lever 8 is thrown completely over to the left, Fig. 2, it willclear the upper end of the cam 5 and permit complete detachment of thestandard from the part 4, by a movement laterally in relation to saidframe part 4.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A cultivator standard provided with an open ended clamp portionhaving a cam surface and adapted to embrace a part of the cultivatorframe, a bail pivoted to the standard, and a cam lever carried by thebail and ada ted to engage the cam on the clamp, said ail being of suchlength that the cam lever may clear the cam on the clamp, when desired.

2. A cultivator standard provided with a substantially U-shaped clamp orloop adapted to embrace a part of the frame of a cultivator and havingon its free end and When the lever is raised the bail and lever uppersurface, an incline or cam, a bail may be swung clear of the free end ofthe pivoted to the standard, and a \cam lever -U-shapedc1amp. 10 carriedby the bail and adapted to bear ::In testimony whereof, I hereunto aflixmy 5 against the incline or cam surface .aforesignature.

said when the lever is depressed, said vbail and cam lever beingproportioned so "that EDGAR XV. BENSON.
